The colossal Mastiff belongs to a canine clan as ancient as civilization itself. A massive, heavy-boned dog of courage and prodigious strength, the Mastiff is docile and dignified but also a formidable protector of those they hold dear. Mastiffs have an easy-care coat, but they shed heavily. Mastiffs need training so they can be easily managed in spite of their size. Mastiffs are not recommended for new or timid owners.
